Issue-based
An article joins an issue, the issue is published
The classic model. An accepted manuscript is assigned to an issue and goes live when that issue is complete.
- Page numbering
- Continuous within a volume: the second issue starts where the first ended. The next value is suggested, never forced.
- Early view
- You can publish an article before its issue is full. It appears as early view and settles into the issue once that is closed.
- Supplements and special issues
- Numbered separately so they do not disturb the pagination of regular issues.
Continuous
An article is published when it is ready
The manuscript reaches readers the day it is accepted, without waiting for an issue. It joins the open issue, which closes on its own at year end.
- Article numbers instead of pages
- An article number replaces the page range, and the citation line is generated accordingly.
- Speed to publication
- The wait between acceptance and publication disappears. For authors this is the most visible difference.
- Archive structure
- Articles are still gathered under volumes and issues, so the archive stays orderly and indexes harvest it as before.
